Comparing Ruma's Top Armature Coils
We feature two standout Ruma ignition coils tailored to different engine types, helping you pick the perfect match.
The first, compatible with Briggs Stratton Twin Cylinder Engines (models like 42A707, 42A777, 422707, 433431, 462707, 463707), carries part numbers 590781, 392329, and 394891. Ideal for MTD and Craftsman riding mowers, this coil delivers powerful sparks for heavy-duty, vertical-shaft applications. It's perfect if your mower handles large lawns and requires robust twin-cylinder performance.
The second option, with numbers 490586 and 591459 (replacing 492341, 491312, 495859, 690248, 715231), suits a broader range of Briggs engines used in Toro, MTD, Craftsman, and John Deere mowers. This magneto armature shines in horizontal-shaft setups, offering quick installation and reliable ignition for everyday riding mowers.
Choose the twin-cylinder model for high-torque engines needing extra spark strength, or the versatile 490586 for standard single-cylinder repairs. Both outperform stock parts in longevity, making Ruma a smart upgrade over basic replacements from Generic Armature Coils.
Common Use Cases for Ruma Armature Coils
These coils are indispensable for homeowners and landscapers maintaining push mowers, riding mowers, and garden tractors. Common scenarios include:
- Replacing failed magnetos after seasonal storage.
- Fixing no-spark issues on Briggs-powered equipment.

Buying Guide: How to Select the Right Ruma Coil
Start by identifying your engine's model and part numbers: check the blower housing or manual. Cross-reference with Ruma's specs for a perfect fit. Consider your mower's usage: opt for the twin-cylinder coil for demanding jobs, or the standard for lighter duties. Always inspect wiring and gaps during install for optimal results.
